Whether it's new hardware or just a software upgrade however, the contact in layman terms is a review into whether a design (typically one yet to enter EMD) is going to meet baseline requirements (ie if this Band 5 receiver warning capability will work adequately via whatever they're doing with MADL).


Here is interesting document about DARPA MiDAS program:

Program info: https://www.darpa.mil/program/millimete ... tal-arrays

It's not a data link itself, but technology program which can be used as a base to create new very fast and flexible data links and is likely applicable to other applications like radar, ESM and EW systems. This could be MADL 2.0 which there has been some notes in official documents. It would likely need new antennas, new waveform(s) and new software to the SDR to get all the benefits.

Thank you spazsinbad! I need to start attaching these pdfs, so these can be found years later...

A MIDAS based approach would be a wholesale replacement for the aperture (much wider bandwidth that MADL),
the antenna, the receiver electronics and all of the software stack (DDS/SDR, protocol etc.).
